<af:activeImage>

The image component renders an image specified by the source property. Due to performance overhead compared to <af:image>, you should only use this component if you plan to support changing the source attribute through active data, otherwise you should use the <af:image> component.

Events

Type

Phases

Description

org.apache.myfaces.trinidad.event.AttributeChangeEvent

Invoke Application,
Apply Request Values

Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.

Attributes

Name

Type

Supports EL?

Description

attributeChangeListener

javax.el.MethodExpression

Only EL

a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.

binding

oracle.adf.view.rich.component.rich.output.RichActiveImage

Only EL

an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.

clientComponent

boolean

Yes

whether a client-side component will be generated. A component may be generated whether or not this flag is set, but if client Javascript requires the component object, this must be set to true to guarantee the component's presence. Client component objects that are generated today by default may not be present in the future; setting this flag is the only way to guarantee a component's presence, and clients cannot rely on implicit behavior. However, there is a performance cost to setting this flag, so clients should avoid turning on client components unless absolutely necessary.

customizationId

String

Yes

This attribute is deprecated. The 'id' attribute should be used when applying persistent customizations. This attribute will be removed in the next release.

id

String

No

the identifier for the component. The identifier must follow a subset of the syntax allowed in HTML:

Must not be a zero-length String.

First character must be an ASCII letter (A-Za-z) or an underscore ('_').

Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an underscore ('_'), or a dash ('-').

imageMapType

String

Yes

Valid Values: none, server

if a server-side image map is desired, specify "server" and place the image inside a CoreGoLink component. URI of the server-side image map file has to be given as a destination attribute for the goLink component. Default value for imageMapType is "none".

inlineStyle

String

Yes

the CSS styles to use for this component. This is intended for basic style changes. The inlineStyle is a set of CSS styles that are applied to the root DOM element of the component. Be aware that because of browser CSS precedence rules, CSS rendered on a DOM element takes precedence over external stylesheets like the skin file. Therefore skins will not be able to override what you set on this attribute. If the inlineStyle's CSS properties do not affect the DOM element you want affected, then you will have to create a skin and use the skinning keys which are meant to target particular DOM elements, like ::label or ::icon-style.

longDescURL

String

Yes

a URL to a document that contains a long description of the image. This description should supplement the short description.

partialTriggers

String[]

Yes

the IDs of the components that should trigger a partial update. This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too. Identifiers are relative to the source component (this component), and must account for NamingContainers. If your component is already inside of a naming container, you can use a single colon to start the search from the root of the page, or multiple colons to move up through the NamingContainers - "::" will pop out of the component's naming container (or itself if the component is a naming container) and begin the search from there, ":::" will pop out of two naming containers (including itself if the component is a naming container) and begin the search from there, etc.

rendered

boolean

Yes

whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.

shortDesc

String

Yes

the short description of the activeImage component. This text is commonly used by user agents as the image's alt text. Note that for accessibility purposes, all images must specify some value for the shortDesc attribute. For purely decorative images which provide no meaningful information, the value should be the empty string.

source

String

Yes

the URI specifying the location of the image resource.

styleClass

String

Yes

a CSS style class to use for this component. The style class can be defined in your jspx page or in a skinning CSS file, for example, or you can use one of our public style classes, like 'AFInstructionText'.

unsecure

java.util.Set

Yes

A whitespace separated list of attributes whose values ordinarily can be set only on the server, but need to be settable on the client. Currently, this is supported only for the "disabled" attribute. Note that when you are able to set a property on the client, you will be allowed to by using the the .setProperty('attribute', newValue) method, but not the .setXXXAttribute(newValue) method. For example, if you have unsecure="disabled", then on the client you can use the method .setProperty('disabled', false), while the method .setDisabled(false) will not work and will provide a javascript error that setDisabled is not a function.

visible

boolean

Yes

the visibility of the component. If it is "false", the component will be hidden on the client. Unlike "rendered", this does not affect the lifecycle on the server - the component may have its bindings executed, etc. - and the visibility of the component can be toggled on and off on the client, or toggled with PPR. When "rendered" is false, the component will not in any way be rendered, and cannot be made visible on the client. In most cases, use the "rendered" property instead of the "visible" property.Not supported on the following renderkits: org.apache.myfaces.trinidad.core
